UNITED STATES PATENT @OEEicEo LEMUEL BANNISTER AND LORIN kBLODGE'I, OFPHILADELPHIA, PENNSYL- VANIA; SAID BLODGET ASSIGNOR TO SAID BANNISTER.

CONDUIT FOR ELECTRIC CO-NDUCTORS.

SPECIFICATION forming part of Letters Patent No. 301,203, dated July 1,1884.

Application led December 26, 1883. (No model.)

To aZZ whom t may concern.:

Be it known that we, LEMUEL BANNrsTEE and LoRrN BLoDGE'r, citizens ofthe United States, and residents of the city and county of 5Philadelphia, in the State of Pennsylvania, have jointly inventedcertain Improvements in Conduits for Electric Conductors, of which thefollowing is a specification. l

In the accompanying drawings, Figure l is Io a View of a section ofconduit, and a transverse sectional view of an ice-box or refrigerator,with which the interior of the conduit is connected. Figs. 2, 3, and etare views illustrating the manner in which the Wires are sup- I5 portedwithin the pipes, and Fig. 5 a View illustrating the arrangel'nent ofthe conduitsections.

In Letters Patent N o. 282,833, granted August 7 1883, to LemuelBannister, an electric 2o conduit is shown and described, theconstruction of which we prefer to employ in our present system-that isto say, the conduit-pipe is formed in sections, and each alternatesection is divided longitudinally, so that by the re- 2 5 moval of' itsupper half ready access may be had to the wires. rlhe lateralconnections with the conduit are also preferably made at a dividedsection, all of which details are fully set forth in the patent abovementioned, to

3o which reference is made.

The purpose of the present invention is to` provide an economical andpractical way of supporting the wires within the large pipesections ofthe conduit. In the prior patent l 35 above mentioned this is done byinelosing them within tubes which are supported in partitions containedin the large pipe-sections.

Under the present invention each divided section A of the conduit isprovided with one or .to more series of posts, B, on which the wiressockets are formed by flanges c e, projecting inwardly from the wall ofthe pipe. Vith such a construction each post may readily be removed andreplaced, if desired, without disturbing the other posts, and all theposts are 5 5 at the same time held rigidly against any lateral strain.Though We prefer to employ an upper and lower socket, as shown, a singlesocket in the lower half of the pipe-section only may be employed, asthe strain of the 6o Wire will be sufficient to maintain the posts in avertical position.

The intermediate sectionless pipe-sections A may be provided withsuitable Wire-supporting devices, or the strain on the wires may 6 5hold them sufficiently taut so that no support will be required betweenthe posts in one sectional pipe and the posts in the adjoining sectional pipes.

Vith such an organization as has been de- 7o scribed any Wire mayreadily be reached without difficulty by removing the upper half of oneof the pipe-sections. The length of these sections may, of course, bevaried as will be found most convenient in putting them in 75 place inthe ground.

It is desirable to provide some means for securing a dry absorbentatmosphere in the conduit, and We preferably employ an arrangement, suchas illustrated in Fig. .1., in which So is shown an ice-box orrefrigerator, E, having inclined hollow shelves e, on which the ice isplaced and a gutter, e', that carries loff the drip pings. The air isdrawn into the refrigerator through valvesf by the pump D, and is passedSi', through the pipe G into the conduit, and may be allowed to escapethrough exits X.

We do not herein claim any method ofl se; curing a dry absorbentatmosphere in the conduit; but We deem it Idesirable to employ the 9omethod herein shown and described.

Ve claim as our inventionl. The combination, substantially as set forth,of an electric conduit, and the independ ently-supported andindependent]y-removable 9 5 posts or wire-supports, arranged in atransverse series across the conduit.

2. The combination, substantially as set upper and lower sections of thepipe, which` 50l divided or formed in two parts, and n trans verseseries of indepeinlently-reinovable wirei 5 sustaining posts or supportsmounted in the divided conduitseetions.

In testimony whereof We have hereunto subscribed our naines this 22ddai-y of December, A. D. 1883.
